nginx doesn't log anything

I'm running a FreeBSD 9-Stable server, with nginx.
My configuration is here:

user www www;
worker_processes 5;
error_log /var/log/nginx/nginx-error.log;
events {
    worker_connections 1024;
}
http {
    include mime.types;
    include fastcgi_params;
    index index.html index.htm index.php;
    default_type application/octet-stream;
    log_format   main '$remote_addr - $remote_user [$time_local]  $status '
    '"$request" $body_bytes_sent "$http_referer" '
    '"$http_user_agent" "$http_x_forwarded_for"';
    sendfile on;
    autoindex  on;
    tcp_nopush on;
    tcp_nodelay on;
    ignore_invalid_headers on;
    gzip on;
    server {
        listen 127.0.0.1;
        server_name localhost;
        location /nginx_status {
        stub_status on;
        access_log off;
        allow 127.0.0.1;
        deny all;
        }
    }
    server {
        listen 80;
        server_name localhost cubox.me *.cubox.me;
        access_log /var/log/nginx/nginx-access.log main;
        root /var/www;

            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /var/www/$fastcgi_script_name;
        }
    }
    server {
        listen 80;
        server_name yk.cubox.me yubikey.cubox.me yubico.cubox.me;
        access_log /var/log/nginx/nginx-access.log main;
        location / {
            proxy_pass http://localhost:8000;
            proxy_set_header  X-Real-IP  $remote_addr;
        }
    }

        }
    }
    server {
        listen 80;
        server_name munin.cubox.me;
        access_log /var/log/nginx/nginx-access.log main;
        root /var/www/munin;
    }
    server {
        listen 443;
        server_name munin.cubox.me;
        access_log /var/log/nginx/nginx-access.log main;
        ssl on;

        ssl_prefer_server_ciphers on;
        root /var/www/munin;
    }

}

My problem, actually, is that I dont have any log! /var/log/nginx/nginx-access.log or -error.log are empty. The server is running, restarted after config edit.

drwxr-xr-x  27 root  wheel       512 31 déc 14:45 var
drwxr-xr-x   6 root        wheel    1,5k  1 jan 22:41 log
drwxr-xr-x  2 www     www       512B  1 jan 21:28 nginx

-rw-r--r--  1 www  www  0  2 déc 16:48 nginx-error.log

The both files are not written by nginx, but the user www has access to them.

The server doesn't have any other problems, and is running fine.

Solution 1:

I think the problem could come from this piece of setting:

server {
    listen 127.0.0.1;
    server_name localhost;
    location /nginx_status {
    stub_status on;
>>>>access_log off; <<<<<<<<<<<<<<<< You are setting them to be off
    allow 127.0.0.1;
    deny all;
}
